American Idol alum Clay Aiken on Thursday officially filed paperwork to run for Congress as a Democrat in North Carolina.

The 35-year-old singer is looking to unseat Rep. Renee Ellmers, a Republican who represents North Carolina's 2nd congressional district in the U.S. House.

Aiken turned in his paperwork at the State Board of Election in Raleigh surrounded by friends, family and supporters.

“I am comfortable with myself,” Aiken told reporters. “I am comfortable with the campaign we're running. I am positive that people are going to vote for the person who they think will do the best job, who they think can win in November.”

Aiken, who came out gay in 2008, five years after his second-place Idol finish, on the cover of People magazine, announced his congressional bid in a video on February 5. In the 5-minute video, he said that he does not believe his sexual orientation will be an issue.

According to the AP, Aiken's campaign has raised more than $100,000.
